Is the 1999 penny larger in diameter than normal? It might be what is called a " Texas Cent" in the US. The penny is hammered between two pieces of leather until the copper plating cracks and falls off. What's left is the zinc core.

I have the same mystery coin, of the same date.
It is larger diameter, thicker with a railroad style rim (both sides spilling outside the collar) and slightly bent (probably bent within the collar).
I think it is a legit struck coin, I don't have any photos of mine (yet) but I am tempted to sent it to PCGS for their opinion. I realize, being bent in the collar that it will come back ungraded (Genuine) but I think the planchet itself is a slightly larger zinc planchet that was struck in the 1-cent press... seeing a second one (yours) has given me something to think about...

Is there a way to test if its zinc without damaging the coin?

In my opinion these coins are most probably a form of post mint alteration.

How does one explain it being thicker _and_ larger diameter Ken?

I concur that this is a Texas Cent. The coin shows proportional expansion of the die-struck design on both faces, which is physically impossible. The proportional expansion, lack of copper plating, and bumpy surface are all characteristic of Texas cents.

I thought Texas Cent, but the coin didn't seem to lose any thickness. Is that normal? (I'd love to see a side-by-side shot of the thickness with the normal cent.)

Quote:I concur that this is a Texas Cent. I completely disagree Mike... I revert back to my earlier question: how do you explain the larger diameter as well as a significantly greater thickness with that method? The laws of physics don't quite account for that, given how Texas cents are made...

Considering that the outer rim of both sides seems raised like a burr, if you were to shave of the excess, I think it would indeed be a tiny bit thinner. Caliper test shows the grayish cent to be approx 1/2 millimeter or 1/32" thinner. Would need a micrometer to do a more precise thickness test.

I'd be interested in it's thickness just before the collar. It almost looks like it's been knurled. Got a micrometer?

(if you were to shave of the excess, I think it would indeed be a tiny bit thinner.) But wouldn't that also make it weight less? John1

Hmmm...hadn't thought of that but yeah, I guess it would. But then one could argue that without the copper coating, it would weigh less anyway.
